On April 27, 2026, the Solana Foundation published a blog post that sounded suspiciously like someone finally turning off the kitchen blender and admitting that the sunrise isn’t caused by the coffee machine. It confirms that its core developer teams have, in rare moments of collective seriousness, agreed on a future quantum security plan. The network confirmed that both teams selected Falcon, a shiny new digital signature system, and early working versions have already been built.
Solana Foundation said quantum threats may still be years away, but preparing early is the better move.
Two Core Developer Teams Agree on One Solution
What makes this update more important is that two major Solana developer teams, Anza and Firedancer, studied the problem separately and reached the same result, which is either impressive or mildly creepy depending on your tolerance for coincidences and coffee.
Both teams selected a post-quantum signature system called Falcon.
That matters because these teams build critical infrastructure for Solana validators. If both groups independently support the same model, it adds confidence that the plan is practical and technically strong.
What Is Falcon, And Why Did Both Teams Pick It
Falcon is a new digital signature system made to protect against future quantum computer attacks. It is stronger than Solana’s current system, Ed25519, if quantum machines become powerful enough one day.
Both teams picked Falcon because it offers strong security while staying fast and lightweight.
This is important because Solana handles many transactions, so it cannot use a system that slows the network down too much.
A new report on Solana’s quantum readiness is here, from @anza_xyz and @jump_firedancer.
TLDR: Quantum is still years away, and if and when it materializes, the work to migrate Solana is well-researched, understood, and ready to deploy as described below.

Falcon is also trusted by experts. It was chosen by the U.S. National Institute of Standards and Technology (NIST) as one of the approved post-quantum security systems.
No Immediate Changes Needed
For now, users do not need to do anything. Solana says today’s systems remain safe, and no urgent upgrade is required. But the roadmap is already forming.
“Quantum is still years away,” adding that migration plans are “well-researched, understood, and ready to deploy.”
New wallets would adopt Falcon first if quantum risks escalate. Existing wallets would migrate in a later phase.
Beyond the main network, other projects in the Solana ecosystem are also working on quantum-resistant tools. One example is Blueshift’s Winternitz Vault, which has been active for over two years.
This shows that Solana is not just planning for the future but already testing solutions in real conditions.
